Ticks infesting domestic animals in Italy: current acarological studies carried out in Sardinia and Basilicata regions.

The note reviews published and unpublished data on acaralogical studies carried out by different parasitologists' groups in Sardinia and Basilicata regions. In Sardinia 72 collecting sites were investigated and a total of 4,086 ticks were collected from hosts (cattle, sheep, goats and pigs) and from soil. So far 2,413 ticks belonging to six genera have been identified: Rhipicephalus (67.2%), Haemaphysalis (24.1%), Hyalomma (2.7%), Boophilus (0.7%), Dermacentor (4.9%), Ixodes (0.3%). Host-associated ticks were collected from 50 out of 200 selected farms in Basilicata. About 4,000 tick specimens were collected and 1,794 ticks have been identified (of which 1,215 were adults, 6 larvae and 573 nymphs). The following genera were identified: Ixodes (20%), Rhipicephalus (27%), Hyalomma (31%), Haemaphysalis (18%), Dermacentor (6%). The seasonal distribution of the species identified in the two regions studies is discussed from a geographical and climatic point of view.
